In addition, the features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

The term "and/or" in this article is only an association relationship describing associated objects, which means that there can be three types of relationships, for example, A and/or B. The specific understanding is: A and B can be included at the same time, and they can be separate There is A or B alone, and it can have any of the above three conditions.

Example one

Referring to Figures 1 to 6, the stapler provided in the first embodiment of the present invention includes a body tail plate 313, a battery pack 41, a tertiary tube V3 and a controller. The positive and negative signal shrapnel 313-2 of the tail plate 313 of the body and the signal in the battery pack 41 are connected to the upper and lower plates 41-2 through a mechanical mechanism to output signals for the stapler; the tail plate 313 of the body The power clip 313-1 and the power output conducting piece 41-1 in the battery pack 41 are mechanically connected to output power for the stapler; the controller is used to control the action of the battery board in the battery pack 41.

The stapler and its timing discharge method provided in the first embodiment of the present invention can control the discharge of the battery in the battery pack 41 through the controller. After the body tail plate 313 is connected to the battery pack 41, the controller obtains the duration t of the conduction. When the duration t of the continuous conduction reaches the set duration t0, the controller controls the battery in the battery pack 41 to discharge until the battery voltage reaches a safe value or less, and the controller controls the battery in the battery pack 41 to stop discharging. Among them, due to the application of triode, before the battery is discharged below the safe value, even if the battery is unplugged, it can continue to discharge below the case value. Therefore, it is necessary to ensure that the battery pack has sufficient power output when the battery pack is used to solve the remaining battery after use. The risks caused by the power supply can solve the risks arising from the use of non-original batteries, and reduce the handling requirements and use risks after use.

Among them, the base of the triode V3 is connected to the corresponding pin of the controller, the collector of the triode V3 is connected to the battery board, and the emitter of the triode V3 is grounded.

Among them, the voltage dividing resistor is composed of multiple resistors in parallel, one end of the voltage dividing resistor is connected to the collector of the transistor V3, and the other end of the voltage dividing resistor is connected to the power supply. In this case, the greater the number of parallel resistors connected to the circuit, the smaller the resistance value of the equivalent resistance, the smaller the divided voltage. Conversely, the smaller the number of parallel resistors connected to the circuit, the equivalent resistance The greater the resistance value, the greater the divided voltage. In practice, circuit breakers can also be set on the lines of each parallel resistance, and the opening and closing of each circuit breaker can be controlled by a knob or multiple switches, so as to change the resistance value of the equivalent resistance of the voltage divider connected to the circuit, and control The voltage divided by the voltage divider.

In this case, it is possible to reduce the risk of damage due to accidental force when the body tail 313 and the battery pack 41 are used separately.

Wherein, the contact interface between the notch 5 and the protrusion 6 has a streamlined shape, which can not only increase the aesthetics, but also reduce stress concentration, thereby increasing the service life of the rising tail plate 313 and the battery pack 41.

Among them, the stapler also includes a damping block 7. The damping block 7 is fixedly connected to the outer side of the protrusion 6. In this case, when the battery pack 41 needs to be removed from the body tail plate 313, the friction force between the hand and the human hand can be increased by holding the damping block 7 so that the battery pack 41 can be removed from the body tail The unloading force on the plate 313 is smaller, and the operation is easier.
